【摘要】：光逻辑门是未来全光网络中光信息处理的核心元件,它可以实现高速光包交换,全光地址识别,数据编码,奇偶校验,信号再生等功能。采用微环谐振器设计了一种新型的电光逻辑门,结构通过三个非对称微环组成,分析耦合区的传输矩阵方程得出加载电压信号的变化能够实现微环折射率的变化,利用光强的逻辑开关特性可以实现光门逻辑。计算机仿真验证了工作波长1 600 nm时,实现的高电平50.7 V定义为逻辑1,低电平0 V定义为逻辑0,通过光强变化得出了6位逻辑运算;整个系统的响应时间理论上得到了1.8 ps,运算速率可达近200 Gbit/s。逻辑的双稳态分析中得出:微环发生最大谐振值时对应的控制波长等于微环未发生形变前的谐振波长和偏移量之和;调制可以通过微环谐振波长实现控制。这一研究对于未来全光通信的实现具有一定的意义。
[Abstract]:Optical logic gate is the core element of optical information processing in future all-optical network. It can realize the functions of high-speed optical packet switching, all-optical address recognition, data coding, parity check, signal regeneration and so on. A new type of electro-optic logic gate is designed by using a microloop resonator. The structure is composed of three asymmetric microrings. By analyzing the transfer matrix equation in the coupling region, it is concluded that the change of the loading voltage signal can realize the change of the refractive index of the microloop. The optical gate logic can be realized by using the characteristics of light intensity logic switch. The computer simulation shows that the high level 50.7 V is defined as logic 1, and the low level 0 V is defined as logic 0 when the working wavelength is 1,600 nm. The 6 bit logic operation is obtained by changing the intensity of light. The response time of the whole system is theoretically 1. 8 ps, up to nearly 200 Gbit/s.. In the bistable analysis of logic, it is concluded that the control wavelength corresponding to the maximum resonant value is equal to the sum of the resonant wavelength and the offset before the microloop does not deform, and the modulation can be controlled by the resonant wavelength of the microloop. This research has certain significance for the realization of all-optical communication in the future.
